I was changing batteries in my laser, and when I pressed a button I could not turn it on.
I was trying to screw cap back and forth and 2 times I managed to turn it on, but the moment I just moved it in air a little bit (just so I can place it on a desk) it just stopped working again... (((
I tried different batteries, I screwed cap many times, nothing...
Also I think it was loosing on power and brightness but I cant really teall as I dont have LPM but definitely the "texture" of the diode light (the stripes it has inside) were changing over time (over time span of like a month or something like that)
The time I was using it before this happened I wasnt overheating it or anything like that.

Thankfully its still on guarantee, but I think its better idea to ask you first what to do/what might had happened to it, before sending it back to China...

:cryyy:

EDIT: I tried shorting the battery and end of the host threading with cable and aluminium foil, and it doesnt work...

GSS its glass lens, The diode emits spot with stripes, and those stripes were changing brightness not shape, also it was working fine with the nitecore and olight batteries, just now I cant turn it on, btw about what issue then are you talking about, I just wanted to make sure im buying right batteries and charger.
RedCowboy i tried it many times unscreewing and screewing it back tighter/less tighter, I dont see any "ring"

if you are sure that your batteries are good then its the main body of the laser(driver,diode) hard to make anything more if you are not sure what your doing.best will be to sent your laser to someone for a fix or on the seller if it has a warranty

Leon, I didn't mean to come across harsh
The issue I meant was when you were trying out the different battery's the laser would turn on off and on when screwing the tail switch on..
Forgot about buying from Tommy's sight and having the glass lens..
Have you got it working?

Tommy has a 6 month warrentee that I see and lets hope he honors it without you paying for return shipping..

It does sound very much like an intermittent connection. Probably somewhere in the driver/diode area. Since you say it is under warrantee, I'd contact LPS and see what you need to do to take advantage of it. Hope you don't have to ship back at your own expense as that is not cheap.

Saying there's a warranty and honoring it is a different story..
I'm sure there is a potential for them to last and be fun for quite some time.
Narwhal, do you see enough mass to handle the 3W version? I'm also thinking they use a brass module which is iffy.:undecided:

The upper part of the host of my Thor starts to get warm after about a 40-50secs which is when I start to think about turning it off. This thing could probably just handle 3W but nothing more if you want a decent duty cycle.

Will probably disassemble it at some point to see whats inside. Don't have the right tools right now.

All the specs on all the Thors say the hosts are AL. I know the brass module isn't a good sink but Paul are you sure? Did you try a magnet on yours, as I don't believe its stainless if the magnet were not to stick.
